Useful things to know

Yes. High-security cylinders with security pins, sidebars or restricted keyways are designed to slow an intruder, and they do slow a locksmith too, but they open with the right technique, a decoder made for that keyway, or as a last resort a precise drill through the cylinder followed by a like-for-like replacement. Bring any key card or code card that came with the lock, since restricted keys are cut from those records rather than copied.

Entry comes first and repairs second. Once authority is confirmed the door is opened, staff go in and start their routine, and the locksmith turns to the cause: extracting a broken key, rekeying for a lost one, re-springing a deadlatch or lifting a dropped door. Anything that can wait for a quieter hour, such as rekeying interior doors, is offered as a return visit so the shop floor is not blocked while it trades.

It depends on how the piece is sitting. A protruding fragment in a plug at rest can be out in moments. A deep piece behind lifted pins takes patient work with hooks and spirals. A glued or corroded fragment may mean removing the cylinder and freeing it from behind. Cutting and testing the new key, and any door adjustment, add their own time. The locksmith gives a sense of it after the first look.

Once a month for the first season, throw the deadbolt with the door closed and feel for drag or a stop short of full extension, and press on the strike and hinge screws with a screwdriver to confirm they are snug. Repeat at each change of season, since wood moves with humidity. A door that starts needing a shoulder, or a bolt that catches on the strike lip, wants a small adjustment early rather than a repeat of the original problem.

Because with the door open the bolt is throwing into thin air, and with the door closed it is throwing into a pocket that has moved. A door that has dropped on its hinges, swollen with humidity or been pushed out by thick weatherstripping lands the bolt against the edge of the strike plate instead of through the hole. A chalk mark on the bolt shows exactly where it hits, and the fix is on the frame, not in the cylinder.

You can, and it solves being without a key. It leaves the lost one working, though, which is the half of the problem that keeps people awake. Rekeying takes about as much effort as a trip to a hardware store counter and ends with a new key in your hand and the old one retired. If the key was mislaid somewhere it will never be found and named nothing, a plain copy is a fair choice.

Yes, at every cylinder that was rekeyed. Once the bottom pins are changed, a key cut to the old combination lifts them to the wrong heights and the plug will not turn. The locksmith proves this at each door by trying the old key after the new one, because any door missed from the list would still answer to the old key. That is also why the walk around the property at the start matters: every door meant to be included has to be on the list.

It is worth having. The door between an attached garage and the living space is in practice often the softest way in, since a garage door left open leaves a passage knob as the only barrier. A thumb-turn deadbolt there costs a few minutes a day and closes that gap.

Photographs of each lock from outside and inside, plus one of the door edge showing the latch plate and one of the strike on the frame, tell the locksmith most of what they need. Add the door thickness if you can measure it, whether the door is wood, steel or fibreglass, the finish you want to match, how many doors are involved and whether you want them all on one key.

It is a lock built as a flat rectangular case that sits inside a pocket cut into the edge of the door, rather than through a round hole bored across it. The case holds the latch, usually a deadbolt, the hub the knob spindle turns, and the springs. On the faces of the door you see the knobs, decorative plates and either a keyhole for a bit key or a round cylinder. Most doors built before the middle of the last century carry one.

It depends on who uses the door. Codes suit everyone and need nothing in hand. Fobs or cards are a favourite for children and for anyone who finds small buttons difficult, since a tap does it. Fingerprint readers are convenient for a household of adults but can be fussy with cold, wet or gloved hands in winter, so pair them with a code. Phone control is for whoever wants alerts and remote checks. Most families end up using two of these.

Choosing corrosion-resistant fasteners and a cylinder rated for weather exposure at the outset avoids most of the problem, since plain steel fittings near a driveway or walkway take the brunt of de-icing salt over a winter. For hardware that already shows early corrosion, cleaning and a dry lubricant can extend its working life, while pitted or seized parts are better replaced than fought with season after season. A rinse of the hardware after a heavy salt application is a simple habit that helps as well.

The broken piece is removed first, using extraction tools that grip and draw it out rather than push it further in, and then the lock is opened the usual way. A key rarely snaps in a lock that is otherwise healthy, so the old cylinder is checked afterward, and if wear caused the break, replacement rather than a repeated repair is the sensible next step.

Usually not. It depends on the model. Some electronic locks offer an external contact for a fresh battery, or a mechanical override key behind a cover plate; restoring power this way wakes a dead keypad but does not bypass a lost code on its own. Others have a reset port on the lock body, which sits inside the safe and still needs the door opened by other means first. The locksmith works through that model's own documented procedure before considering anything more invasive.

Not automatically. Fire resistance comes from an insulated, sealed construction that is not necessarily built to resist tools, while burglary resistance comes from thick steel and hardened plate that is not necessarily built to survive a sustained fire. Some units are built and rated to both standards at once, but a fire-only safe left unrated for burglary should not be assumed to hold up against a determined attempt with tools.

They solve different problems. A keypad or smart lock manages who can enter and when, and many have no keyway to pick. A high security mechanical lock resists physical attack and controls key copying without batteries, apps or connectivity. Many businesses use both: electronic access on high-traffic doors and high security cylinders on rooms that must hold regardless of power. The locksmith helps you match the tool to each door rather than choosing one philosophy.

The outside cylinder on an exit door controls entry only, and it can be rekeyed like any other. The inside stays as it must: one push or one turn, no key, no special knowledge, on the exit door itself and on any door on the way to it. A locksmith will not add a keyed device to the inside of an exit, and will point out one if it already exists.

Sometimes, but it depends on the keyway and pinning platform each brand uses; some are compatible with one another and some are not. Where a mix already exists on a property, the assessment identifies which cylinders can be brought into a single hierarchy and which need replacing with a matching platform so every level pins correctly across the whole set of doors.

Yes. The controller keeps a running record of which credential was presented at which door and when, available to the administrator at any time, not only after an incident. It can be checked for a specific door, date, or credential, which is useful for everyday questions as much as investigating something unusual, though it identifies the credential used rather than confirming who was physically holding it.

Panic hardware and fire exit hardware share the same push-to-release action, but fire exit hardware is additionally tested and listed for use on a fire-rated door assembly. That extra listing matters because a fire door has to keep an active latch bolt at all times; it cannot carry a mechanical dogging function the way ordinary panic hardware sometimes can, so the two are not interchangeable on a rated opening.

In most cases, yes. Replacement hardware is chosen to fit the door's existing mortise pocket, bore pattern or narrow-stile prep, so the visit does not usually involve altering the door itself. Re-cutting only comes up when the business specifically wants to change hardware type, for example moving from a knob-and-deadbolt pair to a single mortise lock body.

It changes what happens after the door is open. Entry is the same as any other car. Starting depends on the immobiliser recognising a fob, so if your fob's battery is dead you hold it against the start button or in a marked pocket in the console, which the locksmith shows you. If the fob itself is lost, a new one is programmed where the vehicle's own security system supports it, though some models need dealer credentials, tools or parts first.

Often, yes, for vehicles with a supported conventional key system: the car is opened, a blade is produced by decoding the door lock or retrieving the factory key code, and the immobilizer is reset so the missing keys are erased before new ones are stored. A key-card or phone-key vehicle, or one needing a dealer procedure, follows its own route instead, which is why the VIN is asked for on the first call.

If the original has remote buttons and you want the spare to match, yes: the new key or fob is programmed to the vehicle's receiver so locking, unlocking and any other remote function respond the same way from either key. If a simpler spare is preferred instead, the remote portion can be left out while the chip that starts the car is still fully recognized.

The vehicle generally stays where it is parked, since the equipment used for programming travels to it rather than the other way around. What matters more than the location is that the vehicle itself is present for the visit, since most procedures read information directly from the car as part of registering the new fob.

Many recent models, particularly ones with additional security layers, require a manufacturer-level session that only certain equipment can reach. Older and simpler systems more often allow direct programming without that extra step. The locksmith can usually confirm which situation applies to a specific vehicle from its year, make and model before the visit.

That points toward the barrel itself, debris packed into the keyway, or a key that has bent or worn out of shape rather than a deeper electronic problem. The keyway is checked and cleared first, the key is compared against a spare if one exists, and the barrel is serviced or replaced depending on what that first check turns up.

A dead coin-cell battery is the most common reason, and it is a straightforward fix once the fob is opened. Less often, the fob has lost its pairing with the vehicle or its case has cracked and let in moisture, both of which a locksmith can check and address.

On many machines that carry one. The mechanical cut and the electronic pairing are handled as two separate steps: the key is shaped to fit the lock, then its chip is taught to the vehicle's module using an existing key or programming equipment built for that system, where the maker's own security rules allow it. Both steps are tested with a full engine start, since a key can turn the switch and still fail to start the machine if the chip was never paired.
